Pack in the big case shell after the high voltage integrated capacitor is generally connected through certain series parallel structure by the unit of inside and fill with transformer oil, the connection of capacitor unit then realizes by the terminal of its sleeve pipe.The employed sleeve pipe of existing aggregation type internal element is the silver-colored formula structure of roasting, the porcelain spare of sleeve pipe part adhere to silver powder up and down after be connected with up and down flange cover, last lower flange cover is metal material, and the outside is warded off tin and is handled, upper flange and conducting rod are structure as a whole, conducting rod is the open-core type structure, convenient drawing of going between.The sleeve pipe of this structure is owing to being connected to of lower flange on it and porcelain spare bakes silver-colored formula structure, connection technology is fired in employing, therefore, in the use of product, have electric current to flow through or other heating situations under seepage oil can take place, and withstand shock not, under certain electric current or voltge surge active force, its upper flange tends to come off, and has brought hidden danger for the operation of whole high voltage assembling shunt capacitor.
How to design a kind of capacitor casing, solve the problem that easy to leak oil and upper flange come off easily, this is the technical problem that needs to be resolved hurrily at present.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiency that prior art exists, and a kind of capacitor casing is provided, and rational in infrastructure, sleeve pipe is easy to leak oil not, and upper flange is not easy to come off.
The purpose of this utility model is achieved by the following technical solution: a kind of capacitor casing, comprise conducting rod, the upper flange cover, high tension insulator and lower flange cover, it is characterized in that described conducting rod, the upper flange cover, high tension insulator and lower flange cover are separate piece, described upper flange set upper side cooperates perforate with conducting rod, make conducting rod stretch out the upper flange cover, and high tension insulator is stretched into by the cylindrical hole at high tension insulator center in the conducting rod lower end, folder is with the oil resistant rubber sealing gasket and is connected by the oil resistant fluid sealant between described upper flange cover and the high tension insulator, presss from both sides with the oil resistant rubber sealing gasket between described lower flange cover and the high tension insulator also to be connected by the oil resistant fluid sealant.
To improvement of the technical scheme: the groove that embeds upper and lower flange cover is set on the described high tension insulator, upper and lower flange cover adopts cold weld to form with high tension insulator, make upper flange cover, lower flange cover combine closely with high tension insulator, the upper and lower flange cover of part embeds in the groove of high tension insulator corresponding position.Can prevent to rotate between upper and lower flange cover and the high tension insulator, to satisfy its requirement for mechanical performances such as moments of torsion.
To further improvement in the technical proposal: described upper flange cover, lower flange cover are the integral structure that adopts metal material to make.Its surface need not be carried out coating and handled, can be directly and the metal cabinet of internal element carry out argon arc welding or other forms of welding.
The utility model compared with prior art has the following advantages and good effect:
1, upper flange of the present utility model set upper side cooperates perforate with conducting rod, makes conducting rod can stretch out the upper flange cover, and the cylindrical hole of conducting rod lower end by the high tension insulator center stretches into high tension insulator.The product withstand shock can be born bigger mechanical stress and is not damaged.
2, adopting the mechanical technology roll extrusion to connect between each parts of the utility model forms, make upper flange cover, lower flange cover combine closely with high tension insulator, and by the mating reaction of sealing ring, make product reach good sealing property, prevented the seepage oil of internal element effectively.
3, the upper and lower flange cover of the part in the utility model embeds in the groove of high tension insulator corresponding position.Can prevent to rotate between upper and lower flange cover and the high tension insulator, to satisfy its requirement for mechanical performances such as moments of torsion.
4, it is simple and reasonable for structure, and processing and fabricating is convenient, is easy to promote.
